Upgrade your Ford Focus RS with the CSF Part #CSF7239 aluminum radiator, designed to deliver superior cooling performance in demanding driving conditions. Featuring a 42mm 2-row aluminum core, this radiator significantly enhances heat absorption and dissipation compared to the factory unit. The thicker core, combined with a second cooling row and increased fluid capacity, ensures your engine remains at optimal temperatures during spirited driving or track use. CSF's exclusive B-Tube Technology boosts heat transfer efficiency by approximately 15%, providing improved thermal management over standard oval welded tubes. The multi-louvered fins with a 6.5mm height maximize airflow through the core, further elevating cooling capabilities, especially in hot climates or during high-performance driving.
This radiator is engineered for a straightforward installation, offering a true "Drop-in Fit" that requires no modifications to the OEM mounting points. Constructed entirely from TIG-welded aluminum, it features CNC-machined mounting pins and brackets for precise fitment. Each unit undergoes individual leak testing and pressure testing to ensure reliability and performance. Designed with OEM-style inlet and outlet connections, this radiator maintains compatibility with your vehicle's existing cooling system. The product also includes a 2-year limited warranty, providing added confidence in its durability and performance. Whether you're upgrading your Focus RS for track days or enhancing its cooling efficiency for hot weather, this radiator from CSF is an excellent choice to keep your engine running cooler and more efficiently.
